Allergic bronchopulmonary aspergillosis (ABPA) is an immunological pulmonary disorder caused by hypersensitivity to Aspergillus fumigatus, manifesting with poorly controlled asthma, recurrent pulmonary infiltrates and bronchiectasis. There are estimated to be in excess of four million patients affected world-wide. The importance of recognizing ABPA relates(More)
BACKGROUND AND OBJECTIVE Viruses are important aetiological agents of acute exacerbation of COPD (AECOPD). Their reported prevalence varies from region to region. This systematic review calculated the prevalence of respiratory viral infections in AECOPD. METHODS A systematic search was performed using Medline, and references of relevant articles and(More)
Co-circulation of multiple dengue virus serotypes has been reported from many parts of the world including India, however concurrent infection with more than one serotype of dengue viruses in the same individual is rarely documented. An outbreak of dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS) occurred in and around Delhi in 2006. This is the(More)
OBJECTIVE The objectives were to study the relationships of insulin resistance with generalized and abdominal obesity, and body fat patterning in urban postpubertal Asian Indian children. DESIGN Cross-sectional, population-based epidemiological study. SUBJECTS In all, 250 (155 males and 95 females) healthy urban postpubertal children. MEASUREMENTS(More)
Aedes aegypti mosquitoes are common vectors for dengue virus and chikungunya virus. In areas where both viruses cocirculate, they can be transmitted together. During a dengue outbreak in Delhi in 2006, 17 of 69 serum samples were positive for chikungunya virus by reverse transcription-PCR; 6 samples were positive for both viruses.
Long-term treatment with all trans-retinoic acid (RA) induces neuronal differentiation and apoptosis. However, the effect of short-term RA treatment on cell proliferation, migration and invasion of neuroblastoma cell lines (SH-SY5Y and IMR-32) remains unclear. RA induces expression of tissue-transglutaminase (TGase) and promotes migration and invasion after(More)
Chest tuberculosis (CTB) is a widespread problem, especially in our country where it is one of the leading causes of mortality. The article reviews the imaging findings in CTB on various modalities. We also attempt to categorize the findings into those definitive for active TB, indeterminate for disease activity, and those indicating healed TB. Though(More)
BACKGROUND The pathogenesis of salt and water accumulation in patients with chronic obstructive pulmonary disease is unclear and may differ from that in patients with congestive heart failure due to myocardial disease. This study was undertaken to investigate some of the mechanisms involved. METHODS AND RESULTS Hemodynamics, water and electrolyte spaces,(More)
BACKGROUND Evaluation of tumor-specific circulating DNA in plasma/serum is a promising noninvasive diagnostic and prognostic tool requiring only a blood sample, which circumvents the logistic difficulties associated with the use of invasive procedures for serial tumor samplings during screening of lung cancer. METHODS We reviewed English-language reports(More)
Mycoplasma pneumoniae is a common cause of community-acquired pneumonia. Little is known about the extrapulmonary manifestations of this organism. Numerous central nervous system (CNS) manifestations have been described with M. pneumoniae. CNS involvement is probably the most common site of involvement in addition to the respiratory system. Up to 7% of(More)
